THX Trailer

The famous THX crescendo, Deep Note, is like no other audio mark in the world. But where did it come from?

When THX was founded, the company was looking for a truly unique sound effect. A sound that would test the frequency and dynamic range of a theater’s acoustics and surround sound system, while also letting the audience realize that they weren’t in just any typical movie theater.

Working with the artists and engineers at Lucasfilm’s Skywalker Ranch, THX developed an algorithm that produced a beautiful and mysterious electronic sound. This creation continues to wow and impact audiences around the world and sets the stage for a superior entertainment experience.

A THX trailer consists of stunning audio and visual effects, with each trailer taking on its own personality. A few of the artists that have brought these trailers to life include, John Lasseter at Pixar, who conceived the animated character Tex; Gary Rydstrom, the seven-time Academy Award®-winning sound designer whose credits include "Jurassic Park” and "Finding Nemo;” Skywalker Sound’s Gary Rizzo and Steve Boeddeker; veteran composer, Marco d’Ambrosio; and Van Ling, the renowned visual effects supervisor.
